MediumMetricsAV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition in the Linux kernel's cros ec uart probe() function can trigger a NULL pointer dereference. This occurs when devm serdev device open() is called before serdev device set client ops(), setting SERPORT ACTIVE before serdev->ops is set. The serdev controller receive buf() function assumes that if SERPORT ACTIVE is set and serdev exists, serdev->ops will also exist, which is not the case. This can lead to a kernel NULL pointer dereference.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
